You can call it anything you want. At the end of the day what matters is what you are able to produce in a given period, say 8 hours. How many components where placed during that time. Most engineers do not fully understand that there is generally

I also have a spreadsheet tool for comparative analysis using criterion weighted scoring. It can be used to analyze any decision, and helps groups reach consensus on why a particular alternative is the way to go. As final steps you can also consider

You can put a 15, 32, 45, 54 mm lens on a Topaz. However, the 54mm has no published specs. Standard config would use the 45fov single cam. Remember the larger the fov the lower the resolution. Oh and for you guys out there who like the parts per

| Does sombbody know what DPM rate a good and reliable SMT assembly line (incl. solder paste print, assembly and feflow soldering) has? | DPM is Defects per million, usually measured on components. We run a process consisting of small to medium batch

Grandpa, You got it - Identifying the bottleneck operation is the key. The secret is to design a tool can predict accurately where this bottleneck is. In your formula you can use machine process time, PCB transportation time, part trim time, part in

If you study how the process is done now, it isn't that different from what you describe. Instead of glue, we use solder paste, and instead of spraying it we screen print it. But not that different. For feeding boards we use conveyors instead of rubb

Steve, Part numbers with the same specification are not part of the same BOM. Scenario is, SMT Line #1 builds Products X, Y and Z Product X has a part number #1 that is a resistor with 50 ohm value and a power rating Product Y has a part number #

Hi SMT Frog We are using an upgraded Mydata TP9-1 system to place 0402s. We do an electrical test plus mechanical centering and use the C14 tool. A few things we have observed/learned: 1) Is the machine not picking the part up out of the tape? Po

Good points Ken But the reality of the matter is that we are selling off some fuji equipment that even though it is 1994/1995 still has a sale value of 45-65K Each. I am replacing it with faster systems with 0201 specs. With the margins so razor thin
